STAMFORD — The grassroots organization Save Our Boatyard is planning to unveil a new development plan soon for Brewers Yacht Haven following Bridgewater Associates’ withdrawl of interest from the site last week.

The plan is expected to create 300 jobs, generate a “huge amount” of economic funding for the city and restore the boatyard to its former self, according to Save Our Boatyard founder Maureen Boylan.

“It’s a new and improved boatyard plan that we think everyone will like,” said Boylan in a phone interview Monday.

At a public hearing in March at Stamford Government Center, Boylan and her organization announced they were pursuing a $30-40 million project for the boatyard to bring in hundreds of millions of dollars a year to Stamford from the boating industry.

The plan proposed for the 14-acre property included the construction of buildings for offices, boat storage and repair, yacht sales, a bed and breakfast, general store, ship building museum and restaurant center and space for emergency personnel.

Boylan said the new plan calls for layout changes to the buildings and more open space, among other things.

“It’s restoring and making even better the services that were prior,” she said, adding the cost of the new project will be within the same price range of the previous proposal.

Development company Building & Land Technology was planning to build Bridgewater a new 750,000-square-foot building at the site. It was announced at a 2012 press conference that the building was expected to be completed by 2017 and cost $750 million.

The project failed to launch, though, and was met with strong opposition from local boatyard members.

Bridgewater released a statement last Friday saying it “will not proceed with the move” to the boatyard, which is managed and owned by BLT.

“After careful examination and reflection surrounding the challenges, time, energy, and resources needed to bring the proposed Stamford project to completion, we have decided not to proceed with the move. We are particularly thankful to Governor Malloy for doing his utmost to make this opportunity possible. We are now exploring our other options,” the statement read.

A spokeswoman for the company reiterated that Bridgewater is “exploring options now” when asked if its headquarters would remain in Westport.

Boylan said her group was “thrilled” to hear Bridgewater was no longer considering a move to the boatyard, but that they were open to the company moving their headquarters to other empty spaces in the city.

Michael Pollard, chief of staff for Stamford Mayor David Martin, expressed disappointment with Bridgewater’s announcement. But he said the city will not dwell on the news, but rather move forward to seek other opportunities.

“We very much would have liked them to come, but we respect the fact that they want to look at other venues,” Pollard told The Hour. “We can’t understand because Stamford has so much to offer, but again we understand their right to look at other options.”

Pollard said Bridgewater did not communicate much more to the city other than the statement released to the press.

In a phone interview Monday, Pollard said Martin’s office has not seen Save Our Boatyard’s new plan and could not comment on it.

As for the future of the property, he said: “There are a number of factors and a number of variables, but at the end of the day we have to hear all of the options.”

“We want the mayor to get on board and get the parties together to get a resolution to this,” Boylan said.

Boylan said her organization is putting the “finishing touches” on its new proposed project. She said she could not specify when the plan will be revealed, but that will happen “soon.”
